I am trying to add click through functionality to some pie charts I have created. Adding the itemmouseup listener to the series within the view where the graph is defined works and allows the event handler to be triggered, however I need the event handler to be in a controller. I could not find a component query for a graph series and thus tried to add the event listener to the series after the graph is rendered.

The listener is added and can be seen in Google Chrome's debugging tools, however the event and therefore its handler is never triggered.
